As, the summary above states, one of the most magical things about Van Halen when they started was the feeling that you never knew what to expect next. The fact is all of the songs on this album are excellent, some such as "Little Guitars" and "Secrets" quite exceptional. But what makes this album special for me is "Cathedral". It is an instrumental track that proves that the band are going far beyond just good songs, they were reshaping music itself. After Jimi Hendrix in the late 60's revolutionising how the guiar was both played and perceived, Eddie Van Halen's appearance in the late 70's continued to revolutionise guitar playing, such as the use of "tapping", using two hands at once on the fingerboard, something rarely ever seen before him, his influence however, meant that almost every rock band in the 80's were using this guitar technique. "Cathedral" is a jaw droppping and poignant moment in the development of guitar playing. Believe it or not, that is a guitar you are hearing! Not only is it a beautiful song in its own right, but it shows that Eddie Van Halen was not just content with playing blues licks for a living, he wanted to find the boundaries of music, and break them. With "Cathedral" he did just that.
